Background technique

As a writing tool, the pen is widely used in people's daily life. With the strengthening of people's awareness of environmental protection, there are higher requirements for it. At present, the most widely used are pencils and gel pens. Pencils need to consume a lot of wood, which will damage the environment and affect the ecological balance; the materials of gel pens are mostly polystyrene or modified polystyrene, and its harmful substances cannot Self-degradation, used up and thrown away pens and refills will cause waste of resources and environmental pollution, and pencils and gel pens are not durable and have a relatively short life span.

Utility model content

In order to solve the above problems, the purpose of this utility model is to propose a writing pen, which has a simple structure, is environmentally friendly and durable.

In order to achieve the above object, the utility model adopts the following technical solutions to solve it.

A writing pen, comprising: an alloy nib, a pen holder rod, a pen holder cover and a pen core rod, the alloy nib includes an aluminum body, one end of the aluminum body is provided with a tapered tip, and the axis of the aluminum body is Wrapped with a sodium metal inner core, the sodium metal inner core extends to the cone tip of the aluminum body, the outer surface of the aluminum body is covered with a protective film of aluminum oxide; one end of the pen holder rod has a The other end is provided with a connection port; the pen holder cover is detachably connected to the connection port on the pen holder rod; the pen holder core is hollow and long cylindrical, and the pen holder core is assembled in the pen holder rod. One end of the pen holder core is fixedly connected with the alloy nib, and the alloy nib can protrude from the writing opening on the pen holder rod.

According to the writing pen of the present utility model, the tapered tip at one end of the aluminum body acts as a pen tip, facilitating fluent writing; the axis of the aluminum body is wrapped with a metal sodium core, and the metal sodium core extends to the aluminum body At the tip of the cone, on the one hand, sodium and aluminum are soft and easy to write on paper. On the other hand, they are easily oxidized in the air. After the structure changes, they will appear black on paper. The principle of color development is: Na+ Al+O ₂ (air)→Na ₂ O+Al ₂ O ₃ (black powdery substance), which can ensure the clarity of writing; the outer surface of the aluminum body is covered with a protective film of aluminum oxide, which can prevent the The aluminum body is oxidized by oxygen in the air. In terms of service life, the main material of the pencil lead is graphite, with a relative molecular mass of 12, while the relative molecular mass of the alloy tip is 50. From ρ=nM/v, it can be known that the density of the alloy tip is 5 times that of the pencil lead. , It is conservatively estimated that the service life of the alloy nib is 8000m, which is much longer than the 500m of the general neutral pen refill. The alloy nib of the utility model adopts a structure in which an aluminum body wraps a sodium inner core and is covered with a protective film. The structure is simple, the performance is reliable, the service life is greatly improved compared with pencils and gel pens, and it does not need to use wood and cannot be degraded by itself. High-quality materials will not cause waste of resources and environmental pollution.

The pen holder can be made of copper or aluminum. The pen holder is placed inside the pen holder. The end of the pen holder with the alloy tip fixed corresponds to the writing opening of the pen holder. The pen holder and the pen holder cover are connected through the connection port of the pen holder. When in use, Stretch out the alloy nib from the writing opening of the pen holder to finish writing. After use, put the alloy nib back into the pen holder to prevent the alloy nib from being damaged and prolong the service life.
